Explanation Given Information: The equations with solutions are x 4 − 4 x = 0 ; x = 4 or x = − 4 , 5 x = 6 x − 1 3 ; x = 3 and t + 2 5 − t − 2 4 = 1 ; t = − 2 Explanation: Consider the first equation with solutions as below: x 4 − 4 x = 0 ; x = 4 or x = − 4 Rewrite the equation in two equations and mark as below: Y 1 = ( X/4 ) − ( 4 / X ) Y 2 = 0 Use Ti-83 calculator to enter the above equations: Step 1: Press ON key then press [Y=] key and enter the equations as below: Y 1 = ( X/4 ) − ( 4 / X ) Y 2 = 0 Step 2: Press the 2 nd + WINDOW key and set up any desired values as below, Step 3: Press the 2 nd + GRAPH key and enter the value x = 4 or x = − 4 to get the value. Since, the values of Y 1 and Y 2 in the table are all equal at x = 4 and x = − 4 , that means x = 4 and x = − 4 is the solution for x 4 − 4 x = 0 . Consider the second equation with solutions as below: 5 x = 6 x − 1 3 ; x = 3 Use Ti-83 calculator to enter the above equations: Step 1: Press ON key then press [Y=] key and enter the equations as below: Y 1 = ( 5 / X ) Y 2 = ( 6 / X ) − ( 1 / 3 ) Step 2: Press the 2 nd + WINDOW key and set up any desired values as below, Step 3: Press the 2 nd + GRAPH key and enter the value x = 3 to get the value table

Equations and Inequations

Equations and inequalities describe the relationship between two mathematical expressions.

Linear Functions

A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
